Flotation of mixed copper oxide and sulphide minerals with

From previous flotation investigations of mixed copper oxide and sulphide minerals using xanthate and hydroxamate collectors it was hard to distinguish the impact of the alkyl hydroxamate collector on sulphide recovery as the sulphide and oxide minerals occurred naturally together. In the case of the Minto operation the copper oxide and sulphide minerals occur in separate ore deposits and can

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION

The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching. The ore with 4.21% copper grade used in this study was obtained from Çorum-Dangaz region of Turkey. Native copper, cuprite (Cu 2 O), tenorite (CuO), and malachite (Cu 2 (OH) 2 /CO 3) were the main copper minerals in the test sample. Quartz, calcite

A New Application For Flotation Of Oxidized Copper Ore

In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant. It was established that recovery of copper and cobalt

Mechanism and application on sulphidizing flotation of

01/01/2019· The flotation result of actual ore proves that the NaBX+DDA truly has good effects on the sulphidizing flotation of copper oxide. 3.3 Micropolarity of malachite surfaces The micelle concentration formed by collectors in the malachite particle suspension was determined by measuring the micro-polarity of pyrene. In aqueous solution, the I3/I1 ratio was 0.5:1−0.6:1; in micelle solution, the

Improving the efficiency of oxide copper–cobalt ores

Abstract Sulphidising flotation of oxide copper–cobalt ores with sodium hydrosulphide used as sulphidising agent is common practice in Katanga, Democratic Republic of Congo. From laboratory investigations, sodium hydrosulphide proved to enhance flotation selectivity of copper and cobalt towards the gangue minerals, while ammonium sulphide emerged as a strong non
